STUMP-PULLER.

SPECIFICATION forming part of Letters Patent No. 425,671, dated April 15, 1890.

Application filed December 1'7, 1839. erial No. 334,081. (No model.)

To aZZ whom it may concern.-

Be it known thatI, GEORGE HARVEY, acitizen of the United States, residing at Forestville, in the county of Sonoma and State of California, have invented a new and useful Stump-Puller, of which thefollowingisa speciifioation.

This invention relates to stump-pullers of that class in which a vertical capstan is used to wind a rope or chain which has been previously connected to the stump; and it has for its object to construct a device of this class which shall possess superior advantages in point of simplicity, durability and general efficiency.

With these ends in view the invention consists in the improved construction, arrangement, and combination of parts which will be hereinafter fully described and particularly pointed out in the claims.

In the drawings hereto annexed, Figure 1 is a perspective view of my improved stumppuller with one of the inclined beams removed. Fig. 2 is a longitudinal vertical sectional view of the same. Fig. 3 is a horizontal sectional view taken on the line 03 0c in Fig. 2. Fig. 4 is a perspective detail view showing the parts constituting the drum of the capstan separated from each other.

Like numerals of reference indicate like parts in all the figures.

The frame of my improved machine comprises the sills 1 1., which are suitably connected by means of cross pieces or braces 2. Centrally between the sills 1 1 is arranged a heavy block 3, which supports the drum of the capstan. A frame 5, composed of inclined beams 6 6, supporting a heavy cappiece 7, is suitably mounted upon the sills and secured upon the latter against vertical displacement by means of brace-rods 8, extending over the cap-piece 7 and down through the sills, on the under sides of which they are provided with nuts 9. The upper side of the cap 7 is provided with grooves 10 to accommodate the upper part of the brace-rods 8. v

11 designates a vertical shaft, which is mounted in the base-block 3 and cap 7. Upon the lower end of said shaft is arranged a ratchet-wheel 12, which is provided on its upper face with upwardly-extending lugs 13, by

means of which it is coupled to the drum 14, thelower end of whichis provided with notches or recesses 15 to engage the said lugs. The portion of the shaft above the drum 14 is squared and provided with a vertically-sliding clutch 16, adapted to engage recesses 17, formed in the upper edge of the drum. The clutch 16 is provided with an annular groove 13, to engage a lever 19, which is mounted upon a cross-bar 20, connecting two of the frame-bars 6. By means of this lever the clutch may be lifted out of engagement with the drum, and may be supported in this position by means of a hook or catch 21, pivoted to the front side of the cap 7.

A spring-actuated pawl 22, pivoted upon one of the blocks 3, serves to engage the ratchet-wheel 12 when the device is in operation.

Upon the upper end of the shaft 11 is mounted a casting 23, having upwardly-extending bails 24, in which isfitted a sweep or lever 25. The latter is provided with a sliding clevis 26, which may be secured in any desired position by means of a set-screw 27, for the attachment of the draft.

The ends of the sills are provided with pivoted bails 28, adapted to receive stakes 29, by means of which the device may be secured in position for operation upon the surface of the ground.

From the foregoing description, taken in connection with the drawings hereto annexed, the operation and advantages of my invention will bereadily understood. A chain 32 is made fast to the stump' which is to be extracted, and said chain is then connected by means of a suitable hook with the end of a wire cable 33, which is wound upon the drum of the capstan. The latter is then rotated, the speed and power being regulated by adj usting the sliding clevis uponthe sweep at a proper distance from the axis upon which the said sweep rotates. The clutch is then thrown into engagement with the drum or Windlass and the wire rope or cable coiled upon the latter until the stump has been extracted. The clutch may then be disengaged from the drum and the cable be unwound from the latter.

Having thus described my invention, what by Letters Patshaft and adapted to engage the drum, sub- 1 stantially as set forth. e 2. In a stump-pul1er, the combination, with a ratchet-wheel having upwardly-extending lugs, of the drum provided at its lower end with recesses to engage said lugs and the pawl engaging the said ratchet-wheel, substantially as set forth.

3. In a stump-puller, the combination of the frame constructed substantially as-described, the shaft having a squared portion, the ratchet-wheelhavin g upwardly-extending lugs, the drum having recesses to engage said lugs, the clutch mounted slidingly upon the squared portion of the shaft and adapted to engage the upper end of the drum, the adjusting-lever engaging an annular groove in said clutch, a catch to support said adjustinglever-in a raised position, and a pawl adapted to engage the ratehetwheel at the lower end of the drum, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

GEORGE HARVEY.
